? rainfall temperature soil type, depth, fertility altitude LGP(length of growing period) evapo transpiration
rainfall (icarda 1year data, NBDC low resolution data, reanalysis data) soil data from ICARDA (texture, depth, stoniness, phosphorus, nitrogen, potassium, soil organic matter)
DEM 90x90 LGP
evapotranspiration
icarda rainfall station are only one year, but high resolution and precise. we propose to compare the results with the 2 others source of data we have.
The soil map needs to be generated based on the data collection from ICARDA. This can be a time intensive work...
ponds
slope < 5%
flow accumulation < ???
soil depth and fertility
aridity index <0.65
slope from DEM
flow accumulation map
soil depth/fertitilty
aridity index (FAO)
flow accumulation map needs to be generated from elevation.
Bench terracing
Rainfall < 1400mm
erosion status
Slope between 12-58%
Not on forest, not on settlements
soil type (?)
rainfall layer (same than crop)
soil erosion layer (from ICARDA soil)
slope from DEM
landuse from ICARDA
rainfall might not be necessary as it the whole area might fall in the relevant range
Hillside terracing
Rainfall < 900mm
slope 10- 50%
Not forest not settlements
rainfall same than crop
soil erosion
land use
soil bunds
rainfall < 1400 mm
slope 3-15%
not on degraded land
rainfall same as crop
slope from DEM
soil erosion
Stone bund
rainfall < 1400 mm
slope 5-35%
rainfall same than crop
slope
stoniness of the soil (derived from ICARDA soil map)
home gardens/papaya
access water
proximity to homestead
river map (settlement map) existing well map/ponds soil depth altitude
a settlement map could be done based on google earth. About 3000 households live in the watershed, generating this map could be very time intensive.
hand dug wells
proximity to non perennial river (200 m)
topographic index (water saturation)
topographic index < 0.8 (threshold to be validated based on the existing wells map)
river layer
Ficus thonningi (Chibha)
proximity to homestead,
livestock intensity
livestock intensity might not be relevant as all the farmers mentions food shortage as an issue = no need for prioritizing
Also it might be very difficult to say something about spatially explicit livestock intensity in a small watershed
small scale irrigation
slope<5%, proximity to the perennial river (1km)
slope
river map
"spate irrigation"
slope<5%, proximity to the non-perennial rivers (1 Km)
slope
river map
Action plan (in bold what needs to be done before coming to Addis)
get exact crop requirement data (Kibru, to be cross-checked with Teklu in Addis)
get reanalyis data from Cornell (Catherine)
get soil data as detailed as possible, row and processed (Kibru)
LGP check resolution and relevance (Catherine)
check feasibility of doing an evapo-transpiration map based on sun radiation, land cover (=10 m resolution) (Kibru)
check resolutions of available evapo transpiration maps (Catherine)
get the river map (Kibru), make sure that perennial and non-perennial is part of the attribute table (ev. add with experts of from FGD N3)
well map (coordinates of the existing wells) (Kibru)
ponds map (Kibru)
create a settelment map (based on imagery/google earth), to be decided later on if really necessary
topographic index at 10 m resolution (Catherine to ask Abisa or Solomon), check the Grass options
create the flow accumulation map (Kibru, to be crosschecked with Solomon in Addis)
check data for livesock in the N3 dataset (Catherine)
Plan for Addis Day 1
meeting with Teklu and Solomon about crop modeling/ topographic index/ flow accumulation/evapotranspiration
finalizing suitability criterias and map selection Day 2
processing the soil data, rainfall data, Day 3
preparing layer for the tool Day 4
populating the Nile Goblet tool for high resolutions testing the suitability maps Day 5
running the final suitability, short reporting
an additional day is needed to produce the evapo transpiration map or the settlement map digitized from Google earth if it turns out that we need this information.
